AIBU to be confused by sibling invite?

I have somehow managed to get my child to 10 without having to hold a birthday party (born at Easter so we always go on hol instead!) so next week we are having our first party. It's at the house, small scale, drop off and go as the kids are all old enough. We invited 6 kids from school and out of this, 2 have asked if siblings can join and my mind is blown! Is this normal?

For context, one of these asked siblings is 3 years older, the other 3 years younger! My daughter doesn't know or play with them. They will be strangers at the party to everyone except their sibling, who will then be forced to stick to them. The party girl won't be as comfortable when 2 out of the 8 guests she doesn't know and didn't invite. I now have to not only buy more stuff, but also think about whether the activities I had planned cater for these new kids who I do not know. And if you're wondering why I said yes, I was kind of blindsided and it was put to me as if this was the done thing. Which having spoken to some other friends about this, it does indeed seem to be normal!

This has blown my mind. Never when I was younger would I have thought to be invited to my sisters parties. And as a parent, what goes through the mind when you ask? I know your other child is the most important person in the world to their sibling, but they mean nothing to the rest of the friend group - and if they did, they'd have got an invite! Am I out of touch on this and do I need to change my attitude? I'm doing my best to accommodate them and hope they have fun, before anyone thinks I'm a terrible grouch! I just feel like Lucky's Dad when he realised the rules of Pass the Parcel have changed since he was a kid 😂

More fool you for saying yes.

The more the merrier, I don't mind! Just baffled as it was 1/3 of the invited guests that asked and something I'd never come across before

It’s definitely not normal to ask if your 13 year old can come!! My 13 year old couldn’t be dragged to a primary school party at a strangers house - how odd and rude of them!

MyLimeGuide · 04/04/2026 18:21

Don't say yes! How unbelievably rude of those parents!

amber763 · 04/04/2026 18:22

It's weird.

But if it was more the merrier you would have invited more of your child's friends.
It seems weird that a 13 year old wants to come to a child's party. There is a good chance these extras will ruin things.

ExplodingCarrots · 04/04/2026 18:24

You say more the merrier but my DD at 10 would have been fuming if I’d agreed to a 7 year old sibling she didn’t know to come to her party. She’s now nearly 13 and definitely wouldn’t want to go to a 10 year olds birthday party. It completely changes the dynamics. The parents are absolutely mugging you off and using you for childcare so they can have a child free afternoon . I’ve never experienced this for a party at home .

Wtafdidido · 04/04/2026 18:26

Always put on the invitation “sorry we are unable to accommodate siblings in this occasion” and if anyone asks just say “No unfortunately we are unable to accommodate siblings “ No explanation needed. It’s cheeky fuckery for parents to expect siblings who have not been invited to attend. You’re not a babysitter.

Tramone · 04/04/2026 18:29

It’s not normal at those ages.

Out of interest, has your son been to others’ birthday events over his ten years, whilst you have never hosted?

Juswannaget · 04/04/2026 18:30

I have three children who all had birthday parties and siblings never came to the parties unless it was a toddler party involving family friends. It was totally unheard of for parties with the older age group . I think it’s very rude to ask and I would definitely have said NO .

Violetparis · 04/04/2026 18:30

It's cheeky behaviour from the parents and I would have had no problem saying no to them.

SquirrelRed · 04/04/2026 18:32

I have a 13 and 10 year old. There is absolutely no way in this world the 13 year old would go to a 10 year olds party. Are the parents planning on staying or dropping a the teenager off aswell?

HelenaWilson · 04/04/2026 18:33

OP, I think you're being used as a free babysitting service for the parents to be child free.

For a 13yo???? Surely she could be left at home for a few hours, or take herself off to one of her own friends, if her parents had something they needed to do. I'm surprised any 13yo would willingly go to a party with a lot of 10yos she doesn't know.

SunSkyes94843 · 04/04/2026 18:34

Normal in reception age as someone with a 4 year old has to stay and if they also have another small child, they can't leave them at home.

But absolutely NOT normal at this age.

Your child is very understanding to put up with it.

The siblings are probably fuming too!!

Basically it doesn't work for anyone EXCEPT the very cheeky parents.

meganorks · 04/04/2026 18:35

It is cheeky, especially as it is at your house. But I imagine it's because they are thinking they can't come otherwise ie no other childcare. I would maybe just reply 'sorry, we don't have room for siblings too. I'm assuming parents will just drop off and pick up later.'

catipuss · 04/04/2026 18:36

We let an older sibling come to a gym party and he hit the (female) instructor because of some perceived slight to his sister. Never again. Weird family and very protective older brother, but didn't see it coming. Profuse apologies to the venue from me, which were accepted fortunately.

Makingsenseofitall · 04/04/2026 18:38

You might not mind but does your dc mind and the other guests? I am surprised you have agreed to it. It’s huge cfuckery from the parents who asked and I really hope it’s ok for you and for your dc. You are clearly a v kind person.

SalmonOnFinnCrisp · 04/04/2026 17:56

At 4 or 5 yeah i get it.

At 13 and 7 those parented are taking the piss. Just say no....

Hard agree.

pinkyredrose · 04/04/2026 18:40

I'd message back and say you were caught off guard and you can't accommodate extra children. Do it for your daughter, she won't want strangers at her first party.

Ps. extra children rarely bring merriment.

RawBloomers · 04/04/2026 18:58

If you're in a culturally diverse place it might be more different expectations than CFery. At school abroad in a very diverse school, quite a few parents were clearly a bit non-plussed by the idea of birthday parties that weren't basically free for alls, bring siblings, bring the cousins who are staying with you, parents more than welcome to stay and socialise, etc. And, to be fair, they threw parties like that that were extravagant and great fun, but still not what my kids wanted for their birthdays.

One or two, the class don't seem particularly fussed on parties. Are you insinuating that you should only accept invites if you intend to return the favour? To let a birthday child who wants his friend there down because I don't intend to one day host them at a party? If so, that's also baffling to me

Even at 4/5 I don't get it. Can you explain to me - and that's a genuine question, I'm not being an arse. Of course I get if there is literally no other childcare options or something happens last min

AmandaHoldensLips · 04/04/2026 19:07

It's people looking for free childcare.

CeciliaMars · 04/04/2026 19:10

Just say no. It’s cheeky.

HelenaWilson · 04/04/2026 19:10

One of the children in question is thirteen! What childcare does a 13yo need for what is presumably a few hours in the afternoon?

Vodkamartini3olives · 04/04/2026 19:16

It wouldn't bother me. When my kids had parties at the house it was always a mix of school friends, siblings friends, neighbourhood kids. Some parents stayed, some dropped off. If it doesn't work for you just say no.
